SETI@home ("SETI at home") is a grid computing (distributed computing in the project's own terminology) project using Internet-connected computers, hosted by the Space Sciences Laboratory, at the University of California, Berkeley, in the United States. SETI is an acronym for the Search for Extra-Terrestrial Intelligence.
Scientific Research
The goal of SETI@home is to detect intelligent life outside Earth. SETI@home searches for possible evidence of radio transmissions from extraterrestrial intelligence using data from the Arecibo radio telescope. The software searches for four signals:
- Spikes in power spectra,
- Gaussian rises and falls in transmission power, possibly representing the telescope beam's main lobe passing over a radio source,
- Triplets — three power spikes in a row,
- pulsing signals that possibly represent a narrowband digital-style transmission.
The process is somewhat like tuning a radio to various channels, and looking at the signal strength meter. If the strength of the signal goes up, that gets attention. More technically, it involves a lot of digital signal processing, mostly discrete Fourier transforms at various chirp rates and durations.

GeoEye-1 Will Be A High-Res Eye In The Sky
Fri, 29 Aug 2008 14:29:00 -0400
The GeoEye-1 satellite will be capable of making out details on Earth just 16 inches across. It will be the highest resolution satellite run by a private company; it's images will be marketed to a range of governments and private customers.
Europe Considers Joining Space-Faring Nations
Tue, 19 Aug 2008 10:35:00 -0400
Europe's space agency reached two milestones earlier this year. A European-built lab was installed at the International Space Station, and Europe launched a robotic cargo vehicle that successfully docked with the station. The European Space Agency is thinking about converting the vehicle so it could take astronauts into orbit.
Tensions With Russia May Hurt NASA Program
Fri, 15 Aug 2008 16:18:00 -0400
The conflict with Russia over Georgia might affect NASA's ability to get astronauts to the international space station after the space shuttle gets retired in 2010. Congress must pass a special waiver by Sept. 30 so NASA can buy Soyuz capsule flights.
What Makes Our Solar System Special?

Researchers say that if the conditions had been slightly different for our solar system, planets could have careened into the sun or been expelled into deep space. Also: A volunteer astronomer spots a strange gaseous object some are calling a "cosmic ghost."
Phoenix Finds A Salt Compound On Mars
Fri, 08 Aug 2008 14:07:00 -0400
NASA's Phoenix Mars Lander has detected a salt found on Earth on the surface of Mars. The salt, called perchlorate, is used in fireworks and rocket fuel. The news follows the recent confirmation of the presence of water on the Red Planet.
Space Company Hopes To Cut Cost Of Launches
